Applicant not Jaimy 7. 1897.4 Senn N. 618,368. Acumin.)

Be it known that we, ADAM SCHLEIDT and WILHELM PEHL, subjects vof the Emperor of Germany, and residents of Wiesbaden, Germany, have invented certain new anduseful Improvements in Cocks, of which the following is a specification.

This invention relates to certain new and useful improvements in cocks or faucets; and it consists, substantially, in such' features of construction, arrangement, and combinations in position for use.

of parts as will be hereinafter more particularly described. 1

The object of the invention is to provide a cock or faucet `comparatively simple in con-` struction and one in which the use of all packing material is dispensed with..

A further object of the invention is to provide means whereby when the cock. is closed there will be no liabilitytodripping, and also to provide forv the ea'symanipulation of the cock as well as the general efficiency thereof in the performance of-'its functions as such.

These and otherV objects we attain by the means illustrated in the accompanying drawv ings, in which'- Figure l is a longitudinal sectional view taken in a horizontal plane to the cock when Fig; 2 is a similar view taken in avertical plane or at right angles to Fig. 1. Fig. 3 is a left-hand end view, a side view, and a right-hand end view on the line l 1, respectively, of the valve and its stem, to-

gether with the safety or pressure-regulating disks mounted upon or carried by the stem.

. Fig.l tis a sectional view taken on the line l 1 of the central part of Fig. 3. Fig. 5 is a crosssectional View taken on the line 2 2, Fig. 2. Fig. 6 is an endview of the cock or faucet,.showing in dotted linesV the coincidence or registry of the ports of the valve with the channels orpassages of the seat therefor in the shell or casing. Fig. 7 is a similar view representing the valve as cut off or when'the inner outlet-passagesa-nd the valve-ports areout of registry or coincidence. Fig. 8 is aview in perspective of the cock or faucet as it appears complete and ready for use. Fig. 9'is a view in detail of the devices l .which coperate with the valve for opening and'closing lthe latter.

Our invention is capable of being embodied in dierent ways; but as a simple and effectiveconstruction' we have selected the form herein shown'and which will now be described. The shell or casing of the cock or faucet is designated atAandwhich, as shown, is formed with vthe usual downwardly-curved mouth portion B, constituting the outlet or discharge. The saidshell or casing has a rearward extension C, which terminates in a reduced screw-threaded nipple D for securing the faucet in place, and intermediate the inner ends of the extension andthe curved mouth portion B is afsolid portion E, having, preferably, two longitudinal passages c f, forming a communication between the hollow extension C and the saidmouth portion or discharge B. The-said passages are preferably arranged at diametrically opposite points, but it is obvious that both the position and number of said passages could be altered or changed to suit requirements. The body of the shell or casing is preferably somev what enlarged at b,and a cavity or recess m is formed therein, leading, preferably, from the upper side of the shell and extending into the solid portion 1E for about one-half the diameter thereof, the said cavity reaching to and communicating with a central longitudinal socket l, formed in the said solid portion.

A suitable thickness'of material is left between the passages e f and the cavity or recess m, and the sides of the latter converge inwardly and are substantially triangular, and they constitute limiting stops or abutments for the valveoperating devices to be described.

The inner extremity of the solid portion E Visdished or concaved and constitutes a seat for a substantially conical and rotary valve a, `carried on a longitudinal stem i', the said valve being formed with longitudinal ports c d, adaptedeto coincide or register with the ypassages e f and the said stem extending at its inner end beyond the valve and resting or having its bearing in the socket l. The valve vcould be operatcd'to be turned on and effin many different ways; but as a convenient way we fasten in an opening 7L, in the inner end of the stem thereof, at the side the inner end of a pin g, having a radial movement back and forth between the two convergent sides of the cavity m, and the upper end of this pin extends beyond the side of the shell a short distance, so as to enable the pin to be conveniently manipulated for opening and closing the ports of the valve. The said pin can be moved back and forth in the recess m as far as permitted by the sides of the latter, and this of course is the limit of movelnent of the valve in either direction, since the stem of the valve is turned with the pin. rl`he said pin g could be disposed in various ways to operate the valve; but preferably we employ a twopart ring n n, fitting and turning within an annular groove formed in the enlarged part b of the shell. The two parts of this ring are hinged together at 2, and their free extremities are formed with semicylindrical projections o 7s, which are screw-threaded exteriorly to receive a knob or button The outer extremity of the pin g is received between or within the portions k 7c', and it is obvious that by taking hold of the knob and turning the ring in its groove the pin g will be turned and consequently the valve. In the position of the knob as shown in Fig. 6, for instance, the ports of the valve will be in coincidence with the passages cf, and the cock is then open, and in the position represented at Fig. 7 the ports will be brought to a position substantially at rightangles to the passages, and the cock will then be closed.

It will thus be seen that we have provided a very simple and effective faucet; but in addition to the features described we also provide means for effecting a diminution of wa ter-pressure in high-pressure conduits, and thus prevent shocks or hammering of the cock as well as the bursting of the conduit. Such feature of our invention, it will be understood, is equally applicable to cocks or faucets of other constructions than thatherein represented. Thus we provide the valvest-em of a length about equal to the extension C of the shell, and we provide the same with a number of disks (three being shown in the present instance) p, q, and r. Each of these disks is provided with a central opening through which one end of the valve-stem extends, and these disks may be secured rigidly to the stem, in which case they would rotate therewith, or they may be secured rigidly with the casing, in which case the valve-stem would be supported and turn within the central openings. The outermost of said disks is formed with longitudinal passages p', while the remaining ones of the disks are formed with diagonal passages or openings q',crossin g each other, as shown. The form and arrangement of the openings described give to the iniiowing water a spiral movement, and the pressure of the water is thereby diminished with no liability to bursting of the cock.

It is obvious that immaterial changes could be made in the construction and arrangement of the several parts, and therefore without limiting ourselves to the precise details shown and described IVe claiml. In a valve or cock, the combination with a casing provided with inlet and discharge openings, and an intermediate wall, said wall being formed with a conical seat, a passage, a central socket, and a cavity intersecting the socket and extending to the exterior of the casing, a conical valve upon the inside of the Wall adapted to the seat thereof for controlling the passages of the wall, said valve having a stem which extends into the socket, a ring encircling and adapted to turn upon the casing, and devices within the cavity of the wall connecting the valve-stem and ring, substantially as described.

2. In a valve or cock, the combination with a casing provided with inlet and discharge openings, and an intermediate wall, said wall being formed with one or more passages, a central socket and a cavity intersecting the socket and extending to the exterior of the casin g, a rotary valve for controlling the passages of the wall, provided with one or more ports adapted to aline with the passages of the wall and with a stem which extends into the socket of said wall, a ring encircling and adapted to turn upon the casing, and devices within the cavity of the wall connecting the valve-stem and ring, substantially as described.

3. In a valve or cock, the combination with a hollow casin g provided with an exterior annular groove and a dividing-wall within the chamber of the casing formed with one or more passages, a socket and a cavity intersecting the socket and the exterior annular groove, a rotary valve for controlling the passages of the wall provided with a stem which extends into the socket of said wall, a ring adapted to turn within the annular groove and connections within the cavity between the ring and valve-stem, substantially as described.

4-. A cock or faucet provided with interior longitudinal passages leading to the discharge, and provided with a cavity having convergent sides, and with a longitudinal socket leading to said cavity, a rotary valve having a stem turning in the socket, and formed with ports to register with the passages, a pin working in the cavity and connecting with the stem, and a two-part ring turning in a groove in the shell and provided with the semicircular projections 7a, 7d, embracing the outer end of the pin, and the knob or button, substantially as described.

5. A cock or faucet provided with interior longitudinal passages leading to the discharge, a rotary valve having ports adapted to register with said passages, and the disks arranged to the rear of the valve, and provided respectively with the straight and di- IOO IIO

' agonal passages,substantia1ly as described and for the purpose set forth.

6. In a Valve or cock, the combination with K a casing provided With inlet and discharge openings, a rotary valve within the casings intermediate the said openings, a ring upon the exterior of the casing having separated ends, means for securing the ends of the ring together and connections intermediate the lo ring and valve, extending through the casing, foroperating said valve, substantially as described.
